The most recent water sampling in these two wells showed <br /> concentrations of TBA between the drinking water and non-drinking water standards,but no other <br /> constituents. <br /> MW-5 is within 5 feet of an on-site electrical line. MW-5 water samples were ND across the board during the <br /> sampling events in 2013. <br /> MW-8 is within two feet of several buried electrical lines under Country Club Blvd, and within five feet of buried <br /> telecom lines. MW-8 is also in the main east-bound traffic lane, making well box removal problematic. MW-8 <br /> water samples were ND across the board during the sampling events in 2013. <br /> Well SP-G is within three feet of the same electrical line that passes close to MW-1. <br /> Well SP-K is within two to three feet of electrical, water,and sewer lines. <br /> VW-2 is within three feet of the on-site stormwater drain line. <br /> Except for MW-8,the surface construction of these wells should be removable using vacuum equipment and <br /> hand tools, allowing us to employ standard pressure-grouting techniques and remove the top five feet before <br /> placing a grout cap. Because of its sensitive location,Cardno ATC recommends pressure grouting MW-8 and <br /> leaving the well box in place,filling the well box with grout and using the box and lid to maintain a traffic safe <br /> condition. <br /> Jim Kundelt <br /> STAFF GEOLOGIST <br /> CARDNO ATC <br /> T '' <br /> Phone(+1)209.579.2221 Fax(+1)209.579.2225 Mobile(+1)209.996.2767 <br /> Address 1117 Lone Palm Avenue,Suite 201,Modesto,CA 95350 <br /> Email'ii m.kun(iert c&cardno.com Web www.cardnoatc.com"'www.cardno.com <br /> This email and its attachments may contain confidential and/or privileged information for the sole use of the intended recipient(s).All electronically <br /> supplied data rust be checked against an applicable hardcopy version which shall be the only document which Cardno warrants accuracy.If you are <br /> not the intended recipient,any use,distribution or copying of the information contained in this email and its attachments is strictly prohibited.If you have <br /> received this email in error,please email the sender by replying to this message and immediately delete and destroy any copies of this email and any <br /> attachments.The views or opinions expressed are the author's own and may not reflect the views or opinions of Cardno. <br />
